Ellen DeGeneres commissioned a show-within-a-show called 'The Bro Show' -- we know, that's a lot of shows -- and the first guest was Lady Gaga, who tossed back beer and rocked red flannel, paired with maj heels. She was game to bro down.

It's all about sports, beer and cars, and hosted by producer Ross in his man cave. Because when we think dude stuff, we think Mother Monster. Not! But that's what made this skit so funny.

Gaga was a sport, saying she bench presses like 15 lbs., and she asked Ross about his disco stick. She also gifted him with a bun wig and would only participate in an arm wrestling match with him if he wore it -- so he did.

Plus, she taught him to dance and to bump and grind those hips, bringing a dose of femininity to 'The Bro Show.'

Gaga also sat down for a lengthy chat with 'Ellen,' which you can watch here.
